Musiyano uripo pakati peRF isolators neRF circulators

Mukushandiswa kunoshanda, maRF isolators nemaRF circulators anowanzo taurwa panguva imwe chete.
Chii chiri hukama huripo pakati peRF isolators nemaRF circulators? Chii chiri musiyano?
Chinyorwa chino chichatarisa pakukurukura nyaya idzi.
Chinopatsanura mafungu emagetsi eredhiyo, chinozivikanwawo semudziyo unidirectional, chishandiso chinotumira mafungu emagetsi eredhiyo kune rumwe rutivi. Kana mafungu emagetsi eredhiyo akapararira akananga mberi, anogona kupa simba rese kumutoro uye kukonzera kudzikira kukuru kwemafungu anoratidzwa kubva kumutoro. Hunhu uhwu hwekutumira hune directional hunogona kushandiswa kusiyanisa kukanganiswa kwekuchinja kwemutoro panobva chiratidzo.
MaRF circulators masisitimu ekutumira mabranch ane hunhu husingadzokorore. Maferrite RF circulators anoshandiswa zvakanyanya maY-shaped junction RF circulators, ayo anoumbwa nemitsara mitatu yematavi yakagoverwa zvakaenzana pakona ye120 ° kune mumwe nemumwe.

1,Chii chinonzi RF isolator?
Chinopatsanura mafungu emagetsi eredhiyo, chinozivikanwawo semudziyo unidirectional, chishandiso chinotumira mafungu emagetsi eredhiyo kune rimwe divi. Kana mafungu emagetsi eredhiyo akapararira akananga mberi, anogona kupa simba rese kumutoro uye kukonzera kudzikira kukuru kwemafungu anoratidzwa kubva kumutoro. Hunhu uhwu hwekutumira hune divi rimwe chete hunogona kushandiswa kusiyanisa kukanganiswa kwekuchinja kwemutoro panobva chiratidzo. Tichitora chinopatsanura chinofambisa nharaunda semuenzaniso, tsanangurai mashandiro eferrite RF isolator.

Zvishandiso zvinopatsanura simba remagetsi zvinogadzirwa zvichibva pamhedzisiro dzakasiyana dzekuchinja simba remagetsi eferrite pama wave modes anotumirwa munzira mbiri. Zvinowedzera ma attenuation plates padivi pe ferrite sheet, uye nekuda kwekusiyana kwenzvimbo dzinogadzirwa nemativi maviri e transmission, electric field yema wave inotumirwa munzira yekumberi (- z direction) inorerekera kudivi risina ma attenuation plates, nepo electric field yema wave inotumirwa munzira yekumberi (+ z direction) inorerekera kudivi re attenuation plates, nokudaro zvichiita kuti basa re isolation re small forward attenuation uye large reverse attenuation riitike, sezvakaratidzwa muMufananidzo.2.

2,Chii chinonzi RF circulators?
MaRF circulators masisitimu ekutumira mabranch ane hunhu husingadzokorore. Maferrite RF circulators anoshandiswa kazhinji maY-shaped RF circulators, sezvakaratidzwa muMufananidzo 3 (a), ayo anoumbwa nemitsara mitatu yematavi yakagoverwa zvakaenzana pakona ye120 ° kune mumwe nemumwe. Kana simba remagineti rekunze riri zero, ferrite haina magineti, saka magineti kumativi ese akafanana. Kana chiratidzo chapinda kubva kumutsara webazi "①", simba remagineti sezvakaratidzwa muMufananidzo 3 (b) richashamiswa panosangana magineti. Nekuda kwemamiriro akafanana emabranch "②, ③", chiratidzo chinobuda muzvikamu zvakaenzana. Kana simba remagineti rakakodzera rakashandiswa, ferrite inosvibiswa, uye nekuda kwemhedzisiro yeanisotropy, munda wemagetsi sezvakaratidzwa muMufananidzo 3 (c) unoshamiswa panosangana magineti. Kana simba remagineti rakakodzera rikashandiswa, ferrite inobatidzwa nemagineti, uye nekuda kwemhedzisiro ye anisotropy, pane kubuda kwechiratidzo pabazi "②", nepo simba remagetsi pabazi "③" riri zero uye hapana kubuda kwechiratidzo. Kanawo kupinda kubva kubazi "②", bazi "③" riine kubuda, nepo bazi "①" risina kubuda; Kana kupinda kubva kubazi "③", bazi "①" riine kubuda ukuwo bazi "②" risina kubuda. Zvinogona kuonekwa kuti rinoumba kutenderera kwe "①" → "②" → "③" → "①", uye nzira yekudzokera shure haina kubatana, saka inonzi RF circulator.
